Inhaler with Mouthpiece Having a Microbiological Protective Function

ABSTRACT

The present invention relates to an inhaler with a novel mouthpiece having a microbiological protective function. The inhalers are used for administration of a pharmaceutical substance, substance formulation or substance mixture.

Inhaler with mouthpiece having a microbiological protective function The present invention relates to an inhaler with a new mouthpiece that has a microbiological protective function. The inhalers are used for administering a pharmaceutical substance, substance formulation or mixture of substances.

In order to inhale the active substance effectively, the patient has to bring the mouthpiece of the inhaler into contact with the oral mucosa (lips, oral/pharyngeal cavity).

Mouthpieces of the inhalers on the market are usually made of plastics such as polyethylene, polypropylene, ABS (acrylonitrile/butadiene/styrene) and the like

The oral mucosa in all humans contain a variably large number of all kinds of bacteria and other microorganisms which may possibly be pathogens.

Thus, the mouthpiece of an inhaler is contaminated during use. The patients and the users of inhalers are encouraged to clean the mouthpiece after using the inhaler. This cleaning process is carried out with varying results, depending on the personal habits of the patients, their age and how ill they are.

It is therefore desirable to improve the hygiene status of the mouthpiece for an inhaler, irrespective of how it has been cleaned by the patient.

The problem of the invention is to provide an inhaler which has a mouthpiece with a microbiological protective function.

This problem is solved by means of an inhaler according to claim 1. Advantageous features are the subject of the subsidiary claims.

The problem is also solved according to the invention by an embodiment in which the mouthpiece for an inhaler is made of plastics with silver ions incorporated therein.

Preferably, the plastics are polymers, thermoplastic polycondensates, polyadducts, modified natural substances such as e.g. rubbers or mixtures of these plastics.

Most particularly preferred here are polyolefins, vinylchloride polymers, styrene polymers, polyacetals, polyamides, thermoplastic polyesters and polyarylethers or mixtures of these plastics.

Examples of these plastics are polyethylene, polyvinylchloride, polyoxymethylene, polyacetal, acrylonitrile/butadiene/styrene (ABS), acrylonitrile/styrene/acrylic ester (ASA), polyamide, polycarbonate, poly(ethyleneterephthalate), poly(butyleneterephthalate) or poly(phenylenether). Such plastics may be obtained for example from Messrs Ensinger of Nufringen, Germany.

Plastics with incorporated silver ions are used for example in the manufacture of refrigeration equipment for reducing or inhibiting the growth of microorganisms such as bacteria, yeasts, fungi and other micro-organisms.

Additives which contain silver ions for incorporation in the plastics are commercially available. The silver ions contained in an additive known to the skilled person may be incorporated in the plastics together with a standard commercial dye during the manufacture of the mouthpiece according to the invention. Alternatively, the silver ions contained in the additive may be added to the plastics using an inorganic carrier material. The mouthpiece is produced by conventional methods known in the art (e.g. injection moulding).

The essential advantage of the invention is that the plastics with the silver ions incorporated therein inhibits the growth of micro-organisms and particularly bacteria while having and retaining a neutral flavour. Even after frequent used, there are no signs of wear that would affect the beneficial qualities of the mouthpiece according to the invention.

The flavour neutrality of plastic with incorporated silver ions is all the more surprising as silver is one of the (non-toxic) heavy metals, which are normally not flavour-neutral.

Experiments with inhalers having a mouthpiece according to the invention showed a reduced growth of micro-organisms. This was apparent particularly with the following types of bacteria:

Aureobasidium pullulans, Bacillus cereus, Bacillus thuringiensis, Chaetomium globosum, Enterobacter aerogines, Escherichia coli, Gliocladtum virens,

Klebsiella Pneumoniae,

Legionella pneumophila, Listeria monocytogenes, Mycobacterium tuberculosis, Porphyromonas gingivalis, Proteus mirabilis, Proteus vulgaris, Pseudomonas aeruginosa, Saccharomyces cerevisiae, Salmonella gallinarum, Salmonella typhimurium, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus agalactiae, Streptococcus faecalis, Streptococcus mutans, Trycophyton malmsten, Vibrio parahaemolyticus.

It was apparent particularly with the following types of yeasts and fungi:

Stachybotrys,

Aspergillus niger, Candida albicans, Penicillium funiculosum.

Inhalers that can be fitted with the mouthpiece according to the invention include any of the devices (inhalers) currently on the market.

They are preferably powder inhalers, soft inhalers, nebulisers or propellant-operated metered dose aerosols, which may be single- or multi-dose devices.

Powder inhalers are known from the prior art, e.g. from EP 0 703 800 B1 or EP 0 911 047 A1, which disclose a powder inhaler consisting of a dish-shaped lower part and a similarly dish-shaped cover. After placing the capsule in the capsule holder the patient can press an actuating member which cooperates with at least one pin that can be pressed into the capsule holder. The pin pierces the capsule and the medicament is released. The patient takes the inhalable formulation by inhaling using the mouthpiece provided on the dish-shaped lower part.

Other inhalers are known under the brand names HandiHaler®, Spinhaler®, Rotahaler®, Aerolizer®, Flowcaps®, Turbospin®, AIR DPI®, Orbital®, Directhaler® and/or described in DE 33 45 722, EP 0 591 136, DE 43 18 455, WO 91/02558, FR-A-2 146 202, U.S. Pat.

The present invention preferably relates to an assembly according to FIG. 1 comprising an inhaler for inhaling powdered medicaments and a two part capsule, wherein the inhaler comprises the following elements: a) un upwardly open, cup-shaped lower part (1) which has two opposing ports (2) in its casing and at the edge of the opening has a first hinge element with a joint pin (3), b) a plate (9) that covers the opening of the lower part (1) and comprises a second hinge element, as well as a screen holder (11) with a screen (10), c) a countersinkable capsule holder (4) for accommodating the capsule, which is constructed perpendicularly to the plane of the plate on the side of the plate (9) facing the lower part, and on which is provided a head that is movable counter to a spring, the head being provided with one or two sharpened pins (6), d) a mouthpiece (12) with a mouth tube and optionally a gripping aid (17) and a third hinge element, as well as e) a cover (13) that comprises a fourth hinge element, the hinge elements (one) of the lower part, (two) of the plate, (three) of the upper part and (four) of the cover being joined together. In addition, the inhaler comprises an actuating member (7) which serves to open the cover (13) as a result of the closure element (14) on the cover (13) striking the sloping side wall (15) (optionally provided with grooves (16)) of the recess (8), which acts as a sliding surface and releases the cover (13) as the actuating member (7) continues to advance.

The guiding of the pin or pins is substantially carried out by means of two laterally mounted guide arms (18). The guide arms also have the task of holding the actuating member (7) under prestressing. For this purpose the guide arms (18) are provided with end stops at their end remote from the main body, which abut on the guide sleeves of the capsule holder (4) in the resting position of the actuating member (7). The guide sleeves are arranged on the outside of the capsule holder (4). Between the guide arms (18) is mounted a helical spring (5) which extends in its axial direction parallel to the pin or pins (6), the helical spring (5) being matched to the length of the guide arms (18) in such a way that the actuating member (7) is also biased into the resting position. An inhaler of this kind is shown in FIG. 1.
